The electronic apparatus 100 may be electrically connectedand/or in communication with some or all of the components of thesystem. The electronic apparatus 100 may control the connectedcomponents (for example, the LFD apparatus, the projector, etc.). Theelectronic apparatus 100 will be described below in detail withreference to FIGS. 2A and 2B.

The portable apparatus 200 may be remotely connected to or may be incommunication with the electronic apparatus 100 to manage and controlthe system. The portable apparatus 200 and the electronic apparatus 100may be connected with each other in a wired or wireless manner using anetwork connection apparatus (for example, a router or a sharer). Theportable apparatus 200 may manage the electronic apparatus 100 and thecomponents which are connected with the electronic apparatus 100 using acenterstage management system (CMS) application installed in theportable apparatus 200 or the electronic apparatus 100. The portableapparatus 200 may transmit control signals to the connected electronicapparatus 100. The control signals may include control signals capableof outputting contents to the LFD apparatus 260 and the projector 280and control signals capable of downloading contents from the outside tothe electronic apparatus 100.

The proximity sensor 220 detects a user approaching a set area (forexample, within approximately 1 m from the screen 10) of the screen 10or the LFD apparatus 260 as non-contact or contact. The proximity sensor220 which detects the user's approach may transmit analog or digitalsignals corresponding to the detected user's approach to the electronicapparatus 100.

Various types of the proximity sensors 220 may be provided. Theproximity sensor 220 may include a magnetic type proximity sensor, aninductance type proximity sensor, a high-frequency oscillation typeproximity sensor, a capacitive type proximity sensor, an infrared typeproximity sensor, a camera for closed circuit TV (CCTV), and the like.

The proximity sensor 220 may be provided at a position (for example, aposition where the shadow of the proximity sensor 220 is not displayedon the screen 10) where the proximity sensor 220 is not interfering withthe content projected from the projector 280. In addition, the proximitysensor 220 may be positioned in an area between the screen 10 and auser.

The touch panel 240 receives a touch of the user. The touch panel 240may receive a single-touch or multi-touch by a user's body (for example,fingers including the thumb) or an input unit (for example, a styluswhich is not shown). The input unit is not limited as long as it candetect a touch input on the touch panel 240 corresponding to varioustouch detection methods.

The touch panel 240 may transmit analog signals corresponding to theinput user's touch to a touch panel controller (not shown). The touchpanel controller may convert the received analog signals to transmit theconverted signals to the electronic apparatus 100. The electronicapparatus 100 may calculate a position (for example, X and Ycoordinates) corresponding to the user's touch using the receivedsignals.

The touch panel 240 may be implemented as a capacitive type touch panel,a resistive type touch panel, an infrared type touch panel, or anacoustic type touch panel, but the touch panel 240 is not limitedthereto.

The touch panel 240 is positioned between the support frame 245 and theLFD apparatus 260. The touch panel 240 may be coupled to a bezel or backcover (not shown) of the LFD apparatus 260 (for example, using adhesive,adhesive tape, or a joint member such as a screw, and the like).

The touch panel 240 may be integrally formed with the LFD apparatus 260.The touch panel 240 may be implemented in a top area (for example,on-cell scheme) of a display unit (not shown) of the LFD apparatus 260or an inner area (for example, in-cell scheme) of the display unit (notshown) of the LFD apparatus 260. The thickness when the touch panel 240and the LFD apparatus 260 are integrated with each other may be reducedcompared to the thickness when the touch panel 240 and the LFD apparatus260 are separately formed. A weight supported by the support frame 245when the touch panel 240 and the LFD apparatus 260 are integrated witheach other may be also reduced compared to a weight supported by thesupport frame 245 when the touch panel 240 and the LFD apparatus 260 areseparately formed. In addition, a size (for example, a depth of thesupport frame 245 is reduced) of the support frame 245 may be alsominimized when the touch panel 240 and the LFD apparatus 260 areintegrated with each.

The support frame 245 may accommodate the coupled touch panel 240 andLFD apparatus 260. The support frame 245 may support the coupled touchpanel 240 and LFD apparatus 260. In addition, the support frame 245 maybe fitted into the opening 10 b of the wall 10 a. The vertical andhorizontal widths of the support frame 245 are small so as to minimize(for example, to reduce) the interference with the content projectedfrom the projector 280.

The LFD apparatus 260 displays a synchronized content received from theelectronic apparatus 100. The content received from the electronicapparatus 100 is synchronized with the content output from the projector280. The content displayed in the LFD apparatus 260 may be a contenthaving an UHD resolution (for example, approximately 4,000×2,000 pixels)that is approximately four times an FHD resolution. The UHD resolutionmay include 4,096×2,160 pixels or 3,840×2,160 pixels, for example.

In the embodiment of the present invention, a 4K-resolution content maybe used as the term referring to a content having a resolution of UHD ormore. The LFD apparatus 260 may be a display apparatus capable ofoutputting a content having the UHD resolution. In addition, the LFDapparatus 260 may be a display apparatus capable of outputting a contenthaving the FHD resolution.

In the embodiment of the present invention, a diagonal length of adisplay screen of the LFD apparatus 260 may be approximately 1,520 mm(60 inches) or more. In the embodiment of the present invention, adiagonal length of a display screen of a Small Format Display (SFD)apparatus may be smaller than the diagonal length of the display screenof the LFD apparatus 260. In addition, the SFD apparatus refers to adisplay apparatus capable of outputting a content resolution equal to orlower than the resolution of the content displayed in the LFD apparatus260. For example, when the diagonal length of the display screen of theLFD apparatus 260 is approximately 2,150 mm (85 inches), a diagonallength of a display screen of an SFD apparatus 290 may be approximately1,160 mm (46 inches).

In the embodiment of the present invention, the display apparatus havinga same diagonal length of the display screen may have a diagonal lengthof a display screen having a margin of approximately ±50 mm. Forexample, when the diagonal length of the display screen is approximately2,150 mm, the display apparatus having the same diagonal length of thedisplay screen may have a diagonal length of a display screen ofapproximately 2,100 mm to 2,200 mm.

While the LFD apparatus 260 outputs the 4K-content resolution, the SFDapparatus 290 may output a 2K-content resolution. The SFD apparatus 290may be a display apparatus capable of outputting a content having an FHDresolution. In addition, the SFD apparatus 290 may display the same4K-content resolution as that of the LFD apparatus 260, and its diagonallength may be shorter than the diagonal length of the LFD apparatus 260.In the embodiment of the present invention, the diagonal length of thedisplay screen of the SFD apparatus 290 may be approximately 1,160 mm(46 inches).

The screen of the content output from the LFD apparatus 260 may be thesame as the screen of the content projected from the projector 280 tothe screen 10. The content output from the LFD apparatus 260 may havethe same screen as that of the content projected from the projector 280to the screen 10, and have a different resolution from that of thecontent projected from the projector 280 to the screen 10. The contentdisplayed in the LFD apparatus 260 may be displayed with a brightness(for example, brighter) different than the brightness of the samecontent projected from the projector 280 to the screen 10. The screen ofthe content displayed in the LFD apparatus 260 may be a part of thescreen of the synchronized content projected from the projector 280 tothe screen 10.

The content which is received from the electronic apparatus 100 and isoutput to the LFD apparatus 260 is synchronized with the contentprojected from the projector 280 to the screen 10.

A variety of types and sizes of products (for example, a refrigerator, awashing machine, an electric range, etc.) which can be displayed in theLFD apparatus 260 may be provided. The size (horizontal length (width) Xvertical length (height): approximately 2,004×1,085 mm) of the LFDapparatus 260 may be larger than an actual size (approximately 908×1850mm) of the displayed product (for example, a refrigerator). For example,the size (for example, an area of the screen) of the LFD apparatus 260is larger than the actual size (for example, an area of the entiresurface of the product) of the displayed product by approximately 1.05times or more. The size of the LFD apparatus 260 may be larger than theactual size (approximately 686×990 mm) of the displayed product (forexample, an area of an entire surface of a washing machine) byapproximately 2.5 times or more. In addition, the size of the LFDapparatus 260 may be larger than the actual size (approximately 740×920mm) of the displayed product (for example, an area of an entire surfaceof an electric range) by approximately 2.5 times or more. In addition,in the case of a small-sized product such as a mobile phone, a note PC,or a tablet PC, the SFD apparatus 290 as well as the LFD apparatus 260having a screen size larger than the small-sized product may be applied.The term “large-size” has a relative meaning, and may be used as theterm referring to a display apparatus having a screen having a sizelarger than the size of the product displayed on the screen.

The LFD apparatus 260 having the size (horizontal length'verticallength) larger than the size of the displayable product may be selectedto be positioned at the opening 10 b of the wall 10 a.

Through the system including the LFD apparatus 260 and theprojection-type display apparatus 280, products having various kinds andsizes may be introduced, and therefore the number of products, the sizeof the space, and costs may be reduced when compared to an actualshowroom. In addition, through the system including the LFD displayapparatus 260 and the projection-type display apparatus 280, productshaving various kinds and sizes may be introduced to users in a singleplace without burdening the users with the need to move around theinside of the showroom, thereby providing a new shopping experience.

The LFD apparatus 260 may be supported by the fixed stand 265. The LFDapparatus 260 coupled to the touch panel 240 may be supported by thefixed stand 265. The LFD apparatus 260 integrally formed with the touchpanel 240 may be supported by the fixed stand 265. In addition, thesupport frame 245, the touch panel 240, and the LFD apparatus 260 may besupported by the fixed stand 265.

The projector 280 enlarges a synchronized 2K-resolution content receivedfrom the electronic apparatus 100 and projects the enlarged content tothe screen 10. The content received from the electronic apparatus 100 issynchronized with the content output to the LFD apparatus 260. Inaddition, the projector 280 may enlarge a 4K-resolution content receivedfrom the electronic apparatus 100 and projects the enlarged content tothe screen 10. The projector 280 may have a brightness of approximately3000 ANSI lumens or more to correspond to the resolution of theprojected content. When the resolution of the content is increased, thebrightness (for example, ANSI lumens) of the projector 280 may beincreased. The projection-type display apparatus may include theprojector 280.

The synchronized content may denote two contents. For example, a contentscreen output from the LFD apparatus 260 may be a part of a contentscreen output from the projector 280. This may be easily determined whencomparing a size (for example, horizontal length×vertical length) of thescreen 10 and a screen size (for example, horizontal length×verticallength) of the LFD apparatus 260.

The synchronized content output from the LFD apparatus 260 may be acontent of the 4K-resolution, and the synchronized content output fromthe projector 280 is a low-resolution content compared to the contentoutput from the LFD apparatus 260. The synchronized low-resolutioncontent output from the projector 280 and the synchronizedhigh-resolution content output from the LFD apparatus 260 may beoverlapped and displayed on the screen 10. In addition, thelow-resolution content in which a screen area corresponding to thescreen of the LFD apparatus 260 is masked may be output from theprojector 280. The high-resolution content may be output to the screenof the LFD apparatus 260, separately from the low-resolution contentincluding the masked screen area output from the projector 280.

The electronic apparatus 100 of FIG. 1A may bereconfigured as the electronic apparatus 100 connected with the touchpanel 240 and the LFD apparatus 260, a first electronic apparatus 101connected with the projector 280, and a second electronic apparatus 102connected with the proximity sensor 220. The electronic apparatus 100,the first electronic apparatus 101, and the second electronic apparatus102 may be connected with each other in a wired or wireless manner. Whensignals corresponding to a user's approach are received from the secondelectronic apparatus 102, the electronic apparatus 100 may control thesecond electronic apparatus 102 to output a synchronized contentcorresponding to the user's approach from the LFD apparatus 260 and theprojector 280.

It will be readily understood by those persons skilled in the art that acomponent of the system connected with the first electronic apparatus101 and the second electronic apparatus 102 may be changed. In addition,the first electronic apparatus 101 and the second electronic apparatus102 may be implemented as a single third electronic apparatus (notshown, 103).

For example, the control unit may stop both the idlevideo output to one of the LFD apparatus 260 and the projector 280 andthe idle video output to the LFD apparatus 260 and the projector 280.

In operation S304 of FIG. 3A, a hooking video is output to the LFDapparatus and the projector.

Referring to FIGS. 5B and 5C, a hooking video 301 is output through theLFD apparatus 260 and the projector 280. The control unit outputs thehooking video 301 to the LFD apparatus 260 and the projector 280 inresponse to the user's approach. The hooking video 301 may include ahooking video 320 output from the LFD apparatus 260 and hooking videos360 and 361 output from the projector 280. The screen size of thehooking video 320 displayed on the LFD apparatus 260 may be smaller thanthe screen size of each of the hooking videos 360 and 351 output fromthe projector 280.

The hooking video 301 may be output from the LFD apparatus 260 and theprojector 280 in such a manner that various food material, vegetables,fruits, and the like are sucked into a storage space of the product (forexample, the refrigerator with all its doors opened) displayed on theLFD apparatus 260 while looking as if they are sucked into a vortex. Thedoors of the refrigerator into which the various food materials,vegetables, or fruits are all sucked are all closed and then at leastone of the doors may be slightly opened. The slight opening of the upperright door of the refrigerator means that the output of the hookingvideo 301 is completed. In addition, when the slight opening of theupper right door of the refrigerator is output and “center stage” isoutput from the projector 280, it means that the output of the hookingvideo 301 is completed. In addition, when the doors of the refrigeratorare all closed as shown in FIG. 4J, the output of the hooking video 301may be completed.

It will be readily understood by those persons skilled in the art thatvarious hooking videos (for example, sudden disappearing and the like)as well as the hooking video 301 which is sucked into the vortex may bedisplayed. The user who approaches the screen 10 may have interest inand fun with the product by the displayed hooking video 301.

The hooking video 301 may be distinct from the idle video 300 shown inFIGS. 4A to 4 j. The idle video is a video output in a standby statewhich is an idle stage, and the hooking video 301 is a video output inan intermediate stage from the idle stage to a product stage.

The content output from the electronic apparatus 100 may be classifiedinto 3 stages. The 3 stages may include an idle stage (not shown), ahooking stage (not shown), and a product stage (not shown).

In addition, one stage may include 3 layers. The 3 layers may be aninteraction layer (not shown) corresponding to the user's touch, aplayer layer (not shown) corresponding to content output, and a sensorand UI layer (not shown) corresponding to the user's approach. One ortwo layers may be activated in the single stage. In addition, the 3layers may be all activated in the single stage.

In the idle stage which is the first stage, only the player layer thatis the top layer in the idle stage is activated. The player layer mayoutput the idle video 300 to the LFD apparatus 260 and the projector 280in accordance with the control by the control unit.

When the user's approach is detected by the proximity sensor 220, theidle stage is changed to the hooking stage which is the second stage. Inthe hooking stage, the player layer which outputs the hooking video andthe sensor and UI layer which receives a user's input are respectivelyactivated. In the hooking stage, the sensor and UI layer is changed tothe top layer overlapping the player layer to be displayed in accordancewith the control by the control unit.

The sensor and UI layer may include a hooking UI for user's input (forexample, touch or hovering). The hooking UI may include icons, buttons,images, or text. The size (horizontal length X vertical length) of thehooking UI of the sensor and UI layer may be the same as the size(horizontal length X vertical length) of the hooking video output fromthe player layer. In addition, the coordinate origin (0, 0) the hookingUI of the sensor and UI layer may be the same as the coordinate origin(0, 0) of the hooking video output from the player layer. A marginexcept an icon area, a button area, an image area, or a text areaincluded in the hooking UI may be transparently displayed.

When a user's input is detected by the hooking UI, the hooking stage ischanged to the product stage which is the third stage in accordance withthe control by the control unit. In the product stage, the interactionlayer which displays the product UI and the player layer which displaysthe product video are activated. In the product stage, the interactionlayer is changed to the top layer overlapping the player layer inaccordance with the control by the control unit. The interaction layermay include a product UI for the user's input (for example, touch orhovering). The product UI may include icons, buttons, images, or text.The size (horizontal length X vertical length) of the product UI fromthe product layer may be the same as the size (horizontal length Xvertical length) of the product video output from the player layer. Inaddition, the coordinate origin (0, 0) of the product UI layer may bethe same as the coordinate origin (0, 0) of the product video outputfrom the player layer. Even in the product UI after operation S304 ofFIG. 3A, the coordinate origin (0, 0) of the product UI layer and thecoordinate origin (0, 0) of the product video output from the playerlayer may be implemented as the same. A margin except an icon area, abutton area, an image area, or a text area included in the product UImay be transparently displayed.

When a user's input is detected by the icon of the product UI, thecontrol unit may output a product video, corresponding to the icon wherethe user's input is detected, to the player layer. When the productvideo is output in the player layer, the player layer is the top layer.When the output of the product video is completed, the interaction layeris changed again to be the top layer in place of the player layer.

When the user's input is not detected within a set time (for example,one minute which is changeable) in the product UI, the control unit maychange the product stage to the idle stage. The control unit outputs theidle video in the idle stage.

In operation S305 of FIG. 3A, a hooking UI is output to the LFDapparatus.

The hooking UI 321 which is the top layer in the hooking stage mayinclude icons, buttons, images, or text which can receive the user'sinput. The hooking UI 321 may overlap on the hooking video 301 output inthe player layer to be displayed. The hooking UI 321 may include an icon325 corresponding to “Touch to Start”. In the hooking UI 321, a marginexcept the icon 325 may be transparently displayed. When the interactionlayer is displayed, the player layer may be positioned as the lowerlayer than the interaction layer.

The control unit may output the hooking UI 321 to the LFD apparatus 260and the projector 280 in response to the detected user's approach.

In operation S306 of FIG. 3A, a first touch is detected in the hookingUI by the touch panel.

Referring to FIG. 5D, a user performs the first touch on the icon 325displayed on the hooking UI 321. The control unit may detect the firsttouch 326 using the touch panel 240 and a touch panel controller (notshown). The control unit may receive a first touch position 326 a (forexample, X1 and Y1 coordinates) corresponding to the first touch 326from the touch panel controller.

The control unit may store first touch position informationcorresponding to the first touch position 326 a in the storage unit. Thestored first touch position information may include an ID for historymanagement, a touch position, a touch detection time, touch information(for example, touch pressure, touch direction, touch duration time, andthe like). It will be readily understood by those persons skilled in theart that the first touch position information stored may differ inaccordance with a scheme of the touch panel 240.

The first touch 326 may be generated by one of the fingers including thethumb or a touchable input unit. The first touch 326 may includehovering, and may be a single touch or a multi-touch.
